Posted Sat Oct 6, 2012, 5:22pm Subject: MDF lower burr mount removal.
I just picked up an older Gaggia MDF (metal body, friction fit hopper) from CL and it needs serious cleaning under the lower burr mount. This version has the square brass post as opposed to the nut. It is supposed to be a left hand thread, but I have found no way to keep the rotor from spinning to allow removal. If anyone has solved this issue, please share. Thanks

Begin at lower bur disc. Three flat head screws hold the bur in place. These may be coated in rancid coffee oils and grinds, so scrape out flat slot for screwdriver to fit into. Remove all three screws. Lift out bur disc. Again, there may be resistance due to coffee build up. Careful not to scrape or damage the steel bur disc. The brass mounting unit should not be removed until every spec of coffee is vacuumed out from chamber. Here's a picture from another post. Good Luck.
